This paper details the promotion of Croatia through a synergy of sport and tourism. The historical development of sport and tourism is presented, and their relationship. The specific context of the Republic of Croatia is given, including a description of its features. Sport is becoming one of the increasingly important motives for traveling. Accordingly, the ongoing development of sports tourism and sporting events is investigated including the effect of participation and achievement of results at large, international competitions. Practical examples of Croatian tourism and sport promotion are analysed. This is followed by applying a research method in the form of conducting interviews with experts, which in turn provided valuable information on the state of sports and tourism as well as their utilisation in promotional activities while emphasising sports. Finally, the conclusion is drawn as to the manner in which sports can support ongoing promotion of tourism.
